1. A command is one instruction
TAKEOFF starts the drone. MOVE 160 moves it 160 pixels. One line means one step in the mission.

Control a drone with simple programming commands
Write a mission script, run it, watch the top-down arena, and study the drone camera view. This page teaches sequencing, coordinates, heading, speed, safety checks and animation logic.
Lesson
How this drone page works
2. Sequence matters
The computer runs the script from top to bottom. MOVE before TAKEOFF is ignored because the drone is still on the ground.
3. Coordinates locate points
The arena uses x from left to right and y from top to bottom. Use GOTO x y to move to a waypoint.
4. Heading controls direction
TURN 90 changes the direction. After turning, MOVE follows the new heading.
5. Safety checks stop bad moves
The simulator checks boundaries, obstacles and battery. When something unsafe happens, the mission stops with a clear message.
6. Animation loop updates the world
JavaScript uses requestAnimationFrame to update the drone and redraw the arena smoothly.
